To all whom 'it 'may concern: y

Be it known'that I, Jniizs C. Pin-ihrs, a

citizen of the United States of America, 1e

'An object of the invention to providea cap vstructure for lthe end of tubes or con? duits which are used to carry electric wires.

'l`his cap is constructed of sonic suitable inlsulating iiiaterial, as poieelaiii. hard rubber,

or other well-known insulating substances.

lt provided with angularl.)l disposed out- .letl openings in the-end portion ot' the capv through which electric wires extend. 'l`liese openings are separated fi'oiii each other wherebiy the wires will be spaced or separated from eaclifother atthe point' where they leave the tube.

A further 'object of the invention vis to provide nieans for quicklyv and efi'ectuall)Y attaching the Cap to the end of the tube, and whereby the cap may be quickly detached -therefroin when necessary.

A s a modification I provide means for. attaching and `detaching the cap to the'end of a pipefthatis not. provided with threads.

t Referring to the drawings forming part lof this application,-Figure 1 is a longitudinal Sectional view of a portion of a pipe or conduit throughthe axis thereof. showy ing the electrical current carrying wires in place and extending through theend thereof. the cap being shown in section, and ill us` (rating in detail the manner of attaching the saine to the end of the pipe, and-showT ing the wires separated or spaced from each other where they leave the tube.l rl"his figure is intended to illustrate the cap as being l.constructed of porcelain. Included in this figure is an end view of the cam construction.-

Fig. 2 shows. a` slightly modified form of cap-attaching means from that. shown in Fig. 1 in whichthe material em loyed pref ei'ably is tlilat knownas molded material. Fig. 3 4is a modification of the'ineans'for'se- .curing the cap to thepip'e. This means is employed' onv a pipe' that is not provided with threads. Fig. 4 'illustrates in detail a.

side elevation 'of the construction of the. attaching means shown in Fig. Shut separated -froni'the cap proper. Fig. 5 is a detailed perspective vimushowiiig the construction' of the clip. Theform illustrated' is that shown in Fig. Q wherein the cap is made of molded material. Fig, 6 is a modification showing the insulating cap with a waterproof hood for use in external work. ThisV figure shows a sect-ion of the modification through the axis of the cap, and Fig. '7 .is a sectional viewn on the line 7 7 of Fig. 6 illustrating the1 manner of attaching the i\\'ateiproo hood to the cap. Fig. 8 is a further modification showing a cap for use when three wires are run through a conduit, and Fig. Owhen tour wires are used.

. I v l.

ieferrin'g to the drawings in detail: a

designates a portion of the tube in which tliewires b for conveying currents of eleeti-icity .arelocated The outer ends of this tube are usually provided with threads, as

vindieatedat c.

(l designates'theeap proper, and, as shown in the several figures, this cap is provided .with openings e that extend at an anvle to the axis of the cap, as' indicated in Figs. 1 and 2. 'lhe wires as they leave the tube o are drawn or passed through the angularly disposed openings e and will ,therefore be separated from each other where they leave the tube ri, as indicated at f.

ln order to quickly attach the cap to the cud ofthe tubea, l provide a clip g that is perforated or has an opening therethrough, as shown at i., which is larger in diameter than the pipe a, so as to readily pass over the threaded portion. The clip is secured to the cap. as shown in Fig. 1 b v means of the in turned ends z' of the prongs 'n which extend intothe opening j-of the cap.

designates a space between the end of the cap and the body portion of the clip g. .Lo-

cated within this space is a nut m. that'is adaptedto be screwed onto the threaded portion c of the pipe whereby the cap is se curely attached to the pipo a. yThe projecting portions ofjthe .nut through the space la 'readily permit .the loperator to inserta wrenc or Spanner so-'as to readily rotate .the nut either While'attaehing or detaching the ca lin Fi 2' (in which the cap is shown as made ogmolded material) the prongs or l arm-portions n of the clipA are securedto the cap by- 'having the insulating. matin-iai molded around the same during the Aprocess of construction or making of the cap;.other Wise the construction shown in Fig. 2 is ex ofclip the arms y0 are preferably'secured to the Capel, as in Fig. 2; that 4isby having the insulating' material molded around the same duringthe pmcess of construction.

` The body portion p of the strip isprovided with twol laterally projecting ears g that are perforated'forreceiving the clamping bolt r, as shown inFig. 3, whereby the clip may be readily secured to the end of the pipe a, as

readily understood. The arms 0- of the clip.

are made as shown'for the reason that when the nut s is turned up, the elasticity of thel same willpermitl the clip to readily bend .and grasp Athe end of the pipe without breakl lng or injuring the cap b. Y e It will be observed that the clip in Figs.

l and 2 provided ,with a recessed portion t for receiving the threaded en d of the tube a, i' with a shouldered portion u, against which the end of the tube strikes when the nutm is tightly screwed against the clip g, whereby the cap is tightly attached to the t'ube.

,Referring now to Fig. 6 of the drawings: The cap d is provided with a waterproof hood 2 that Iis secured to thecap d by means of the'clip 3 which is preferably made of strap iron of suitable thickness. This clip extendsacross the top portion of the hood and downward to the lower edge of the cap where its lower prongs or arms are turned inward, as shown at 4;, thus securely holding the hood in place. The electric wires b are shown 'passing upward through theoutlet openings 5 and then 'downward in thcordinary way,"whereby the water that may collect'on the Wires will drip therefrom in the usual way. As stated, this t'orm of cap is used for outdoor use as distinguished from.

the forms mentioned in Figs. 1 to 5, iuclusive.

Referring to Fig. 8, the cap (l is shown provided with three outlet openings for the i Wires, as shown :it-"G, and this cap is to be used when the three wires are run through aconduit.

Fig. 9 is substantiallty `the same as Fig. 8 in' construction, except that four .outlet openings are shown, as atl 7; otherwise the construction is the same.

It isl understood that the forms illust-rated in Figs. 6 to 9 are designed tobe used inand-are secured tothe end of the pipe as illustratedin thisiglire.`

From thelabove description, it will be seen Vthat I have devised'a very convenient and eiiective insulating cap for closing the end oft-hepipe and one that will atthesame 1 time separatefthe electrical wires .from each other, and' means whereby the cap can be` readily attached to and detached from lthe pipe, keither with a threaded or unthreaded end portion.
